Specification of Letters Patent.

Patented Nov. 23, 1920.

Application filed May 24, 1917. Serial No. 170,640.

Among the objects of the present inven tion are :to provide aconstrnctionby which the brush roll may be readily applied to andremoved from the machine; to provide a new and improved brushconstruction; to provide a new and improved scrubbing or backing roll;means for resiliently holding said roll against the brush, wherebyarticles varying in thickness may be passed be tween the brush andbacking roll; meansfor maintaining the backing roll, out oi en gagementwith. the brush roll when the 1nachine is not in use; adjustableclamping means For seeming the machine to atub or other receptacle; andnew and improved features of construction and combination of parts, allas hereinafter described.

In the accompanying drawings which illustrate an application of myinvention,

Figure l is an .elevational view showing one end of the apparatus andthemanner of securing the same to the back of a Wash tub or otherreceptacle, i

Fig. 2 is a view similar to Fig. 1 taken at the opposite end of theapparatus,

Fig. 3 is a horizontal sectional view taken on line 3--3 of Fig. 1, I

Fig. 4; is a vertical sectional view taken on line 4l4 of Fig. 3.

Referring to the drawings, 1 designates a tub or receptacle havingstandards Qand a cross-member 2 adapted to have the washing machineclamped thereto. Asillustrated and. as preferred, the washing machinecomprises a frame structure including endmemhere or housings 3 and 4.These members 3 and 4 are tied together by means of aseries oflongitudinally extending rods 5, 6, 7 and 8 ext nd na m ne m sing to theother- For securing the washing machine to the tub or receptacle, Iprovide a pair of adjustable clamp-members 9 adapted to be readilyattached to and is engaged from the receptacle and the rods 7 and S.This construction permits the clamps to be positioned at any desiredpoints between the housings. Both of the said clamp-members are ofsubstantially thesame construction and are formed with suitable bearingportions for the receptacle and the rods, and each is provided withthreaded members 10 and 11.

Characteristic and important features of the present invention are thebrusl11'oll 12 and the manner of mounting said roll in the machine. Asillustrated and as preferred, brnsh-roll 12is made up of a plurality ofindependent sections, each. section having a key-way 13 adapted toengage with separate keys 14 located on the drive shaft 15. I find 17formed in the housings 3 and 4. Each of.

the journal-boxes is maintained within its opening by means of a screw18 passed through an apertured lug 19 formed on the journal-box, saidscrew 18 having its inner end located in a threaded hole formed in aface of the housing. 20 and 21 designate collars mounted on drive shaft15 and designed to hold the brush sections against longitudinal.movement on said shaft 15. Collar 20 is internallythreaded and adaptedto engage threads 22 formed near one end of shaft 15. 23 indicate ballbearings for the shaft 15; the respective ends of shaft 15projectthrough said bearings and boxes, and as illustrated, have reducedend portions 24 and 25. End portion 25 has mounted there on a drivepulley 26, said pulley being driven as shown by means of a belt 27 froma drive wheel 28 mounted on an electric n10- tor shaft 29, the electricmotor being diarammatically indicated by the numeral 30.

he opposite end of the drive shaft 15 or roll.

the end 24-. is provided with a pinion Slprovided for the purpose ofactuating, in connection with drive'belt 32 and pinion 33, a p p 7 Fromthe construction herein described and illustrated by the drawings, itwill be understood that the shaft 15 together with its journal-boxes andthe sectional rotary brush may be readily raised from the housings forthe purpose of removing the brushsections or any of them, when sodesired. This may be'accon' plished by loosening the screws 18 andlifting the brush-roll, etc, bodily from the housings. When free fromthe housing, the pinion 31 together with one of the journal-boxes16 isslid free of the shaft 15, then the collar 20 is removed, after heldagainst the brush roll 12 by suitable means including a pair of bellcrank levers 39, springs 40 and tension ad ustingmeans 4:1. gEaeh of thebell crank levers and its cooperating ,parts are independent of ea chother and act independently on the ends of theshaft 37, therebypermitting the sectional scrubbing .or. backing roll 38 or the endportions thereof to be moved independently and thus allow articles ofvarying thickness to be "passed between the brush. and backing rollwithout, however, substantially changing the uniform pressure at whichthe sec tional backing-roll is held against the brush- By making thescrubbing roll in the form of separate members or sections, and looselymounting the same onshaft 37, I am enabled to prevent the articles beingwashed from wrapping or twisting around the scrubbing roll.

In machines of this character it is important to keep the scrubbing.roll out of contact with the brush-roll when the. machine is .7 notbeing used, and I have provided simple andefiicient means Iorthispurpose, ,As illustrated, these means comprise a pair of pivoted-arms42, one located adjacent to each of the brackets 35, with each arm 42having a finger 43.. It will be understood that as the shaft 37 is movedaway from the brush-roll, this movement will cause the arms e2 t0- beraised. sufliciently .to permit the shaft to pass under the said fingers43 and after the shaft passes thereulnlcr, the arms together with thefingers 453 are lowered with the lingers in engagement with the shaft,thereby preventing the shaft from moving toward the brush-roll until thetingers are released.

Motor 30 is supported on an adjustable plate 4 1, the latter beingpivot-ally secured to a bracket 45 by means of a bolt 4:6. The forwardend of plate a-l: is provided witl an adjusting screw 47 entered in athrmded opening in said plate and adapted to make contact with a portionof the frame structure. The purpose of this construction is to enablethe drive belt 27 to be properly adjusted, tightened or loosened asdesired.

ater for washing from any suitable source of supply may be introduced tothe tub through valve-controlled pipe 43 and pipe 49. After a suflicientquantity is supplied I maintain a continuous circulating system throughpipe 49, pipe 50, pump ill, pipe 51, and the distributing pipe 52. Pipe52 is supported from the framework by means of brackets 53 and isprovided with openings 54 through which streams or jets of water areprojected downwardly upon the articles being washed.

What I claim is 1. In a washing machine and in combination, a frame, arotatable drive shaft journaled in the frame, a brush structure carriedby and rotatable with the shaft, a rod carried by and freely shiftablein said frame, a succession of roll sections extending longitudinally ofand loosely mounted on said rod to permit individual movement of thesections, and means at the opposite ends of said rod for resiliently andyicldably supporting the rod, whereby said sections will accommodate forvariations in washing conditions.

2. In a washing machine and in combination, a frame, a rotatable driveshaft journaled in the frame, a brush structure carried by and rotatablewith the shaft, a rod carried by and freely shiftable in said frame, asuccession of roll sections extendinglongitudinally of and looselymounted on said rod to permit individual movement of the sections, andindividual means at each end of the rod for normally maintaining saidsections in a position of contact with the brush structure, said meansincluding a pivoted bell crank lever, and a tellsion device adjustableto vary the general pressure of the rod.

3. In a washing machine and in combination, a frame having end membersprovided with open recesses, a rotatable drive shaft &;

carrying journal boxes at its ends, said boxes being positionable withinsaid recesses. means for removably securing said boxes in position, abrush structure carried by and rotatable with'the' shaft, said shaftbrush lUll lll)

at. In washing machine and in combination, a frame, a rotatable driveshaft journaled in the frame, a brush structure carried by and rotatablewith the shaft, a rod, carried by and freely shiftable in said frame, ascrubbing roll structure loosely mounted on said rod, individualyieldable resiliently-supported mechanism at the opposite ends of therod for normally maintaining said roll structure in aposition of contactWith the brush structure, and means operative at will for locating saidrod in position to maintain said roll structure spaced from and out ofcontact with the brush structure, said means including anormally-inactive pivoted latching device at each end of the rod.

In testimony whereof I afiix my signature in presence of two witnesses.
